After much thought and time spent checking and rechecking my car to see what went wrong with the PRCAI install that made the light come on, I finally figured it out thanks to the 4th gen maximas in New Orleans, LA. (Thanks Matt and Keith). If you put this intake or any other intake on your car and the light comes on. Check to see if you took off the first piece of your intake. If you did then go back and put it back on, because the reason that the light is on is because of the -map/barometric sensor- the sensor that mounts onto the front part of the factory intake. It says boost sensor on it. Anyway I hope that if any of you have this problem that you give this a try instead of going straight to the dealer -bye bye warranty-.
